The Thagadur region, corresponding to the present-day Dharmapuri district of Tamil Nadu, represents one of the most significant centres of megalithic culture in South India. Archaeological explorations and excavations conducted in this region have revealed a wide range of megalithic burial monuments, including stone circles, cist burials, dolmens, urn burials, menhirs, and sarcophagi. These monuments, primarily associated with the Iron Age, reflect complex funerary practices, technological advancement in iron usage, and deeply rooted belief systems concerning death and the afterlife. This paper attempts a comprehensive study of the megalithic culture of Thagadur by examining burial typology, architectural features, grave goods, iron tools, pottery traditions, and associated ritual practices. The study also situates Thagadur within the wider framework of South Indian megalithic culture and explores its cultural continuity into the early historic period.
